SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF HUMUS CONTENT IN AGRO-SOD-PODZOLIC SOILS

Abstract

The express spectrophotometric method for the determination of humus content in different texture agro-sod-podzolic soils is considered. The method is based on close correlation between the values of spectral reflectance at λ=750 nm and humus content in the agro humus horizons of these soils. The economic efficiency of this method is 48.8 % compared to the existing ones.
